STEERING MECHANISM FOR TRACTION -El\TG-I1 \TES.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed August 17, 1906. Serial No. 330,987.

Tov all whom it may concern:

Be it known thatI, SAMUEL S. Rome, a citizen of the United States,residing in the town of Santa Clara, county ofSanta Clara, State ofCalifornia, have invented new and useful Improvements in SteeringMechanisms for Traction-Engines, of which the following is aspecification.

My invention relates to improvements in steering mechanisms for tractlonengines.

The object of my invention is to provide a steering mechanism fortraction engines which may be 0 erated under all conditions of ground orsur ace encountered in the runnin of such engine and which will greatlyfac' itate the steering thereof, and I declare that the following issuch a description of my invention that anyone skilled'in the art towhich it pertains may make and use the same. I I

My invention consists in the novel arran ement and construction of partsdescri ed in the following specification, illustrated in theaccompanying drawing and claimed in the ap ended claims.

Referring to t e accompanying drawing Figure 1 is a plan view of myfront steering wheel for a traction engine. Fig. 2 is a sectional viewof the same. Fig. 3 is a front view of the said wheel as shown in Fig.1, excepting the part shown above the same in Fig. 1 and sustained byarms 16 whichis omitted. Fig. 4 is a side view of the wheel A as shownin Fig. 3 with one half of the hub removed. Fig. 5 is a lan view of oneof the half sections of the w eel hub, showing the spokes of the wheelbroken away, Fig. 6 is a 1clerlig'lral vertical sectional view of thewheel In the drawings A represents a front steerin wheel which is drivenfrom a shaft or aXIe 2 by a spherical bearing 3 turning with said axle,the latter having pins 4 projecting from the same and slidab e ingrooves or channels 5 as shown in Fig. 2 and'Fig. 4 formed in the hub 6of the said steering wheel A and which hub is made in two parts, and isrevoluble and supported within side bearings 7, the latter carryingsegmental bands 8 which are slidable in bearings 9, said bearings beingloosely mounted on shaft 2 between the collars 10 and 11. .The hub 6being formed of two equal circular parts, the said channels 5 arepositioned equidistantly in each part, being of equal size, and thewalls separating the said channels being likewise of equal size. In eachof said circular parts thechannels incline from the inner to the outerend of said Ipart, and the cavity formed-by connecting t e parts beingaccommodated to the curved form of the bearing 3. By the widening of thechannels an increased radius in turning is effected, such radius beingapproximately 76 degrees or 38 degrees on eac side of the center.

The steering mechanism consists of shaft 12 which carries and turns agear 13 and which gear operates a segmental band 14 by medium of a chain15 secured at both ends of the segmental band 14. The said segmentalband 14 has arms 16 projecting to and secured to the segmental bands 8so that the wheel may be turned to any angle that may be required by theturning of gear 13 by shaft 12 in the running of the engine. Thesegmental band 14 is guided in any suitable frame such as shown at 17which should be supported on the main frame of the enme. %he tractionwheel is as shown in Fig. 1. The side bearings have angular andlongitudinal braces as shown in Fig. 3. The segmental band 14 has an armat each end projecting at right angles to the same, and to said arm issecured one end of the chain 15. Any suitable device may be adopted forturning shaft 12.

It is to be understood that while I have illustrated and described thepreferred embodiment of my invention I reserve the right to make allchanges which properly fall within its s irit and scope.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is.

1. In a steering mechanism for traction engines, the combination with afront axle, and a steering wheel mounted thereon to turn from side toside in a horizontal plane, of segmental straps connected to the hub ofsaid wheel at both ends thereof, a pair of arms connected at one end tosaid segmental straps, a segmental band to which the other ends of saidarms are connected, a steering shaft, a sprocket carried by said shaft,and a chain operating on said sprocket and having its ends connected tosaid segmental band, substantially as described.

2. In a steering mechanism for traction engines, the combination with anaxle, a

The preferable form of exterior for steering Wheel mounted thereon toturn from side to side in a horizontal plane, and segmental strapssecured to both ends of the hub of said, Wheel, of a segmental bandhaving arms at its ends, a pair of arms connecting said segmental bandWith the segmental stra s carried by the Wheel hub, a steering sha t, asprocket, thereon, and a chain engaging said sprocket and having itsends connected to the arms of said segmental band.

3. In traction engines, a steering Wheel, an aXle on which said Wheel ismounted to turn from side to side in a horizontal plane, the said Wheelcomprising a hub made in two equal parts having a central cavityprovided with channels Widening angularly from the center of the hubcavity to the outer end of each of the hub parts, a spherical bearingcarried by the axle and operating in said cavity, pins carried by thebearing to engage in said channels, side bearings in which said hubparts revolve, segmental straps secured to said side bearings, and anactuating mechanism connected to said straps for turning the Wheel.

In testimony whereof I al'lix my sign aturc in presence of tWoWitnesses.
